Definitions
- the invention relates to an electronic module with components that are electrically connected to a circuit carrier.
- Such electronic modules have plate-shaped circuit carriers with multilayer rewiring layers.
- Each rewiring layer can have an insulating layer and a wiring layer, as well as through contacts through the insulating layer.
- the plate-shaped circuit board has rewiring layers on one or both sides and is equipped with components on one or both sides.
- a three-dimensional expansion of this plate-shaped concept for modules is possible by stacking components on the circuit carrier. This concept is limited in its wiring technology when wiring a stack of components, has a very complex structure and is cost-intensive to manufacture.
- the object of the invention is to provide an electronic module which can be produced cost-effectively, as well as a method and a device for producing the module.
- an electronic module is provided with a first and a second component with connections on connection sides of the components.
- the electronic Module has a wiring block with contact pads on its outside and with cables in its volume. Connect the cables in their volume, the contact pads on the outside electrically according to a circuit diagram.
- the two components are arranged on different, not opposite outer sides of the wiring block and their connections are electrically connected to the contact connection areas.
- the wiring block according to the invention is not built up in layers, but is based on a plastic volume through which the lines extend according to a circuit diagram.
- the at least six outer sides of the wiring block can thus be provided for equipping with electronic components or components. It is characteristic that with the aid of the wiring block it is possible to arrange components not only on one side or on both sides on a circuit carrier, but also on the edge sides of the wiring block according to the invention.
- the possibilities for designing circuits and for realizing circuits are expanded on the basis of the wiring block according to the invention, especially since any number of line nodes at which a plurality of lines are connected can be provided within the wiring block.
- the routing in the line block is not limited to vertical and horizontal lines or vias. Rather, any cable routing can be implemented in the wiring block at different solid angles.
- the lines within the wiring block can be carbonized plastic if the entire line block consists of a plastic mass.
- Such carbonized lines in a plastic block can during construction of the plastic block or even after the construction of the plastic block by supplying energy.
- Energy is supplied to the macromolecules of the plastic at interfaces or in the volume of a plastic block, so that the plastic is charred in a focus area of the energy source and thus the formation of conductive material by coking and / or sooting inside the plastic.
- plastic block with carbonized lines is that three-dimensional wiring between the contact connection surfaces to be wired can be implemented on the outside of the wiring block without the need for complex rewiring layers or multi-layer substrates or through contacts in the wiring block.
- the wiring block made of plastic with carbonized lines can be three-dimensional and have both vertical and horizontal lines, as well as lines at any desired solid angle, so that effective and short wiring distances can be achieved in the wiring block. This can reduce delays in the runtime within the electronic module, and the cable routing can be planned three-dimensionally.
- passive, such as capacitive or inductive components can also be provided in the wiring block.
- the lines have nanoparticles with carbonized short-circuit paths between the nanoparticles.
- the wiring block has filling materials in addition to the plastic Form of nanoparticles. In order to connect these nanoparticles to form electrical lines, high-energy impulses can carbonize the material between the nanoparticles and thus create a connecting line.
- the lines have anisotropically oriented nanoparticles.
- filling nanoparticles present in the wiring block are initially anisotropically aligned by alternating electromagnetic fields or by microwave excitation and can agglomerate into lines.
- a device for producing an electronic module has a mold for introducing plastic. Two focusable energy sources with an alignment device for guiding and superimposing the focus areas of the energy sources in the volume of the plastic to be introduced are used to form lines of the wiring block to be produced. In addition, the device has at least one casting device for the continuous or layer-by-layer filling of the casting mold with plastic, forming lines in the intended volume of the wiring block.
- the cables can be inserted directly when the mold is filled with plastic using two energy sources, or if it is a transparent plastic, such as an acrylic resin, a wiring block can also be produced from it after the completion of a translucent plastic block the focus areas of the energy sources are guided through the block volume.
- the energy sources can be laser devices which have an attachment or attachment for deflecting the laser beam and for superimposing two laser beams. The light intensity at the intersection of the two laser beams is so high that the plastic is charred or charred at these points.
- a microprocessor is used to control the energy sources and in particular the laser devices, which coordinates the deflection devices for the laser beams in the case of laser devices.
- Such a device has the advantage that it can be expanded as required if larger outer sides are required for the wiring block.
- the focusable energy source has the advantage that lines are created within the plastic at the focal point if this leads to the formation of lines by an alignment mechanism in a predetermined direction.
- a focusable energy source is also advantageous for non-transparent plastics, namely on the one hand to limit the local expansion of the conductor tracks and on the other hand to carbonize the surface of the plastic to a depth limited by the focus.
- the device has a casting device for plastic.
- This casting device serves on the one hand for the continuous or layer-by-layer filling of the casting mold with plastic.
- connecting lines are introduced into the casting block with the aid of the focusable energy sources, so that a wiring block made of plastic is produced.
- outer surfaces form on the bottom of the casting mold, on the side walls of the casting mold and on the top of the plastic mass, which are to be provided with contact connection surfaces at the penetration points of the carbonized lines.
- laser devices are preferred as energy sources and are used for this device for producing an electronic module with a central wiring block.
- electron beam and ion beam systems also provide high precision.
- ultrasound energy sources and microwave devices can be used if flat or layered carbonized areas are to be realized, such as they can be produced, for example, for passive components as capacitor plates in the wiring block.
- the type of energy source also determines the type of alignment device.
- ion beam and electron beam systems are provided with electromagnetic actuators which allow the electron or ion beam to be guided along lines to be formed.
- optical deflection means such as polygonal rotating mirrors and upstream or downstream lens systems, have proven particularly useful in order to deflect a focused laser beam along planned lines in the plastic wiring block.
- a method for producing an electronic module with two components on different outer sides of a wiring block, which has electrical contact connection areas, has the following method steps.
- plastic is placed in a mold to produce a raw plastic block.
- the wiring block is removed from the casting mold.
- contact connection areas are attached to the penetration points of the lines on the outer sides of the wiring block.
- two or more components for an electronic module with their connections can be sen on different and not only on opposite outer sides of the wiring block.
- a further embodiment of the method consists in first producing at least one plastic layer with lines and then implementing further plastic layers arranged on the first layer. By carbonizing the plastic and / or by agglomerating nanoparticles in the respective plastic layer, lines are produced within the layers and from layer to layer.
- the end result is a wiring block that has at least six outer sides on which components of an electronic module to be wired can be applied in a spatial arrangement to one another.
- the invention provides a medium in the form of a wiring block for electronic modules which, after heat has been supplied by means of energy bombardment, has electrically conductive structures or conductor tracks, alternatively such structures can also be created by electromagnetic structuring methods.
- the conductor tracks are created by carbonizing the resin or sintering conductive nanoparticles that are added to the resin as a filler. After completion of the production of the conductor tracks in the casting resin, the plastic is hardened, which can also be done by supplying heat or radiation.
- the resulting wiring block has a cuboid shape, on the outside of which contact pads can be metallized.
- One of the outer sides can serve as a connection surface for a printed circuit board.
- Semiconductor chips can be mounted on the outside in a flip-chip assembly Soldering or adhesive technology can be applied. Damaged semiconductor chips or components can be removed from the outside at any time and replaced by functional components, which makes maintenance, repair and repair easier.
- the wiring block can be used as a circuit substrate multiple times without restrictions. The method for producing such a wiring block offers the possibility of realizing extremely flexible conductor track arrangements with complex rewiring at this production level. In addition, the wiring block can be inexpensively carried out in any three-dimensional wiring form.
